the text in all "Follow TCP Stream" windows;
the text in the help window if we have one up;
all hex dump windows;
when GUI preference changes are to be applied, so that font changes and
"Follow TCP Stream" color changes show up.
Update both the Roman and bold font when the font is changed.
Don't decrement the reference counts on the old Roman and bold fonts
until that's all done.

highlighting of the bytes, in the hex dump window, corresponding to a
selected field.
Also, make "remember_ptree_widget()" static, as it's not used outside
"gtk/proto_draw.c".

"cancel", and "delete" methods, give them:
"fetch" - fetch from the notebook tab any values not already
stored in "prefs", and store them there, but doesn't apply them;
"apply" - apply the settings in "prefs";
"destroy" - clean up any windows created from the tab.
As we no longer have "cancel" methods, we don't have per-preference code
to revert preference values; instead, we have the common preference
dialog box code make a copy of all the current preferences, and, when
the "Cancel" button is clicked, free the current preferences and copy
the saved preferences to it, and apply the preferences.
Add an "Apply" button to the preference dialog box, which applies the
current preferences without closing the dialog box.
Treat a request to delete the preferences dialog box as equivalent to
clicking "Cancel".
Have a "remember_ptree_widget()" routine to remember all protocol tree
widgets, and use the list of those widgets when we set GUI preferences
for the protocol tree widgets, rather than setting the main protocol
tree widget and then using the list of packet windows. Move that code
out of "main.c" to "proto_draw.c", as it's not used by anything in
"main.c", but is used by stuff in "proto_draw.c".
Make the font one of the preferences we can set on the fly for protocol
tree widgets. Also make it something we can set on the fly for the
packet list widget.

as "isprint()" is defined to be "isgraph() or space" (or, historically
speaking, "isgraph()", which came later, is defined to be "isprint()
except for space).
Make the characters in "packet_hex_print()" be "guchar" rather than
"gchar", so that they don't get sign-extended if the 8th bit is set, and
thus don't cause "isprint()" and company to give random answers.

the "Follow TCP Stream" displays; that means we can use the same GTK+
calls to set the scrollbar placement on them that is used to set it on
other widgets.
Keep a list of all the GtkScrolledWindows whose scrollbar placement we
control with the GUI preference item for that, and change them all when
the GUI preference item is changed (which means that the GUI preference
item now applies to the "Follow TCP Stream" window as well as to the
hex/ASCII panes).

I did this:
First, Havoc Pennington, in "GTK+/Gnome Application Development", in
Appendix seciton A.3.88, recommends using GtkCTree instead of GtkTree
because GtkCtree is faster, and GtkTree has limitation on its total row
height: since it must fit inside a GdkWindow, it is limited to 32,768
pixels of height. GtkTree is more flexible with regards to the types of
widgets that can be placed in the tree, but since we deal only with text,
that doesn't matter, at least for now.
Secondly, a GtkTree doesn't allow arrow-key navigation (at least as far
as I could tell). It always bothered me that the up and down arrow keys
worked in the packet list and in the hex dump, but no in the protocol tree.
GtkCTree does allow arrow-key navigation. In fact, GtkCTree is a subclass
of GtkCList (the packet list widget), so they behave a lot alike.
I went ahead and fixed the selection bar which has been bothering Richard
for a long time now. :) In the GUI preferences dialogue, you can now set
both the packet list selection bar and the protocol tree selection bar
to either "browse" or "select" mode. "browse" mode is what you're used to:
the arrow keys move an outline of the selection bar, but do not change
the selection. "select" mode does change the selection when the arrow keys
are pressed. The default behavior is set to "select", which seems more
natural for a first-time user.

In packet_hex_print(), compute (bstart + blen) only once.
In time_secs_to_str(), return a meaningful string when time == 0, instead
of returing pointer to char buffer with old, inappropriate data in it.

of SNA in a packet changes the character encoding from the default ASCII
to EBCDIC.
The hex-printing routines in the GUI code and in the printing code convert
to EBCDIC if appropriate.

dynamically-assigned "ett_" integer values, assigned by
"proto_register_subtree_array()"; this:
obviates the need to update "packet.h" whenever you add a new
subtree type - you only have to add a call to
"proto_register_subtree_array()" to a "register" routine and an
array of pointers to "ett_", if they're not already there, and
add a pointer to the new "ett_" variable to the array, if they
are there;
would allow run-time-loaded dissectors to allocate subtree types
when they're loaded.

store the field_info pointer, from which we can get both "start" and
"length" (and "hfinfo" and "value", which I'm working towards, so that
match_selected, or a new function, and create a display filter based on
the field's name, instead of byte offset ).

the "File/Print" dialog box; "Expand all levels" means that all levels
of the protocol tree should be printed, while "Print as displayed" means
that only those levels shown in the display should be printed.
Free the table of column widths once printing is done.
